Stem cell transplant shows promise for AIDS treatment

Although the news of a second person being cured of HIV through stem cell transplant is exciting and may pave the way for future treatments, experts say the treatment may not work in case of all patients infected with the AIDS causing virus.

“The stem cell transplant primarily involves reprogramming the immune system to be HIV-resistant. But there a small percentage of people who are naturally resistant to HIV infection due to rare genetic mutations known as CCR5-delta 32,” he stressed.

According to a study published in the journal Nature, a man in London, who prefers to remain anonymous, was treated with stem cell transplants from donors with CCR5-delta 32 mutation. It made him resistant to HIV, just like the first cured case of Timothy Ray Brown, better known as the “Berlin patient”, a decade ago.
